where is ghcautoconf.h, DerivedConstants.h and GHCConstants.h

following wiki to make an unregistered build of ghc 6.6.1 on openbsd-powerpc-current target = powerpc_unknown_openbsd host = x86_64_unknown_linux with ghc-6.10.2 "Copy <T>/includes/ghcautoconf.h, <T>/includes/DerivedConstants.h, and <T>/includes/GHCConstants.h to <H>/includes. Note that we are building on the host machine, using the target machine's configuration files. This is so that the intermediate C files generated here will be suitable for compiling on the target system." looking in the target tree after doing ./configure --enable-hc-boot --enable-hc-boot-unregisterised those 3 files doesn't exist, what step am I missing?
